SetParams

Function Usage

Sets the encoding parameters of the encoder.

Restrictions

This parameter passes through the parameters listed in Configuration Parameters to VmiEncoderParams. The restrictions on these parameters are still valid.

Prototype

EncoderRetCode SetParams(const VmiEncoderParams& params)

Parameter Description

The struct declaration of VmiEncoderParams is as follows:

struct VmiEncoderParams {
    uint32_t bitRate = 3000000;
    uint32_t gopSize = 30;
    uint32_t profile = 1;
    uint32_t keyFrame = 0;
    uint32_t rcMode = 2;                        // Rate control mode
    uint32_t crf = 34;                          // CRF bit rate control level
    uint32_t maxCrfRate = 20000000;             // Maximum CRF bit rate
    int32_t vbvBufferSize = 1000;               // Size of the CRF bit rate buffer
};

Return Value Description

Data type: EncoderRetCode

The value can be any of the following:

VIDEO_ENCODER_SUCCESS: The encoder is successfully set.
